1 Claim. (Cl. 15--244) The present invention relates to a lining forsponges of absorbent resilient material.

It is an object of the present invention to provide a lining for spongesof cellulose, rubber or other resilient material that will prolong thelife of a sponge.

Another'object of the present invention is the provision of a lining soconstructed that it will allow full flexibility of the sponge.

A still further object of the present invention is the provision of alining that is water repellant.

A still further object of the present invention is the provision ofsecuring means in the lining.

A still further object of the present invention is the provision of alining having a portion of its side edges tapering.

A still further object of the present invention is the provision of alining for sponges having a channel or recess.

Other and further objects of the present invention will appear in thefollowing detailed descriptionwhen studied in conjunction with theaccompanying drawings, wherein:

Figure 1 is a plan view of the water repellant lining.

Figure 2 is a side elevational view of a sponge mop equipped with thelining.

Figure 3 is a sectional view through the mop showing the head in fulland illustrating the lining positioned in the recess or pocket of themop.

Figure 4 is a sectional view taken on line 4-4 of Figure 2, the mop headand handle being omitted.

In the drawing the numeral represents the lining and it comprises astrip of water repellant material 11, having straight sides 12 andtapering sides 13, and adjacent each end of said strip there is providedholes 14. The tapered side edges allow for variations in the pockets ofdifferent sponges so there will be no binding or wrinkling of the liningwhen placed in the mop and cemented thereto. The inner side walls of thesponge will always contact the entire tapered end portions of the fabricthus avoiding any wrinkling or pinching of said fabric.

2,694,213 Patented Nov. 16, 1954 The lining 10 is cemented into a pocketor recess 15 of a sponge 16, the holes or apertures 14 being intransverse alignment with apertures 17 in the sponge 16, the apertures14 and 17 receiving eyelets 18 that secure the lining to the sponge atthe open end of the sponge.

The inner face 19 of the lining engages the T-shaped rubber head 20 andhandle 21, thus protecting the side Walls of the sponge in the pocket15.

In carrying out the present invention, the outside face of the lining iscovered with an adhesive, the 1in ing placed in the pocket 15 of aresilient sponge, the outside face pressed against the side walls of thepocket 15 until adhered thereto, the apertures 14 and 17' being alignedand an eyelet 18 securing the sponge and lining together. The pocket 15now being lined is ready to receive a resilient mop head 20 that isinserted into the pocket. The sponge 16 is aflixed to the mop head bypassing a cord or lace 22 through the eyelets and tied.

While the present invention has been disclosed in connection withcertain specific embodiments thereof, it is to be understood that theseare by way of example rather by way of limitations, and that theinvention is to be defined by the attendant claim which should be givena scope as broad as is consistent with the prior art.

What is claimed is:

In combination, a sponge having a pocket, a lining for said pocket, anda T-shaped head for insertion in said pocket, said pocket being open atone end and having inner walls, said lining comprising a strip of waterrepellant material tapering along its edges adjacent each end, saidstrip adjacent each end provided with apertures that receive eyelets forsecuring the ends of said strip to corresponding apertures in the wallsof the sponge pocket at its open end, intermediate portions of saidstrip being attached to the inner walls of said sponge pocket andenclosing said head, whereby securing means through said apertures andeyelets will unite said sponge, lining and head.
